Description

식기세척기의 증기배출구 개폐장치 및 개폐방법Steam outlet of the dishwasher

본 발명은 식기세척기의 증기배출구 개폐장치에 관한 것으로, 특히 볼에 의해 증기배출구를 개폐하도록 한 식기세척기의 증기배출구 개폐장치에 관한 것이다.The present invention relates to a steam outlet opening and closing device of the dishwasher, and more particularly, to a steam outlet opening and closing device of the dishwasher to open and close the steam outlet by the ball.

식기세척기는, 도 1에 도시된 바와 같이, 세척조(1)와, 세척조의 중앙하단부에 설치되어 급수된 물을 모아두기 위한 섬프(2)와, 식기선반(12)에 세척수를 분사하기 위한 세척날개(3)와, 상기 세척날개(3)로 세척수를 보내기 위한 세척펌프(4)와, 건조시 세척조 내부의 공기 유입을 위한 송풍팬(14)등을 구비하고 있다. 한편, 식기세척기의 외관을 이루는 아웃케이스(10)의 전방에는 식기를 출입하기 위한 도어(5)가 부착되어 있고, 상기 도어(5)의 상부에는 건조시 내부의 수증기가 외부로 배출될 수 있도록, 도 2에 도시된 바와 같이, 증기 배출구(8)가 설치되어 있다. 이러한 종래의 식기세척기에서, 세척, 배수가 끝나면 세척조(1)내의 물기(습기)를 건조시키기 위해 히터가 작동되어 내부 공기를 가열하고 세척조(1)내의 고온다습한 공기는 도어에 설치된 증기배출구(8)를 통하여 외부로 배출된다. As shown in FIG. 1, the dishwasher includes a washing tank 1, a sump 2 installed at the lower center of the washing tank 2 for collecting water, and a washing unit for spraying washing water onto the dish shelf 12. The wing 3, a washing pump 4 for sending the washing water to the washing wing 3, and a blowing fan 14 for introducing air into the washing tank during drying. On the other hand, the front of the outer case 10 forming the exterior of the dishwasher is attached to the door (5) for entering and exiting the dish, the upper part of the door (5) so that the water vapor during drying to be discharged to the outside 2, a steam outlet 8 is provided. In the conventional dishwasher, when the washing and draining are finished, a heater is operated to dry the water (humidity) in the washing tank 1 to heat the internal air, and the hot and humid air in the washing tank 1 is provided with a steam outlet ( It is discharged to the outside through 8).

또한 세척시에도 내부에서 히터에 의해 물을 가열할 때 발생되는 수증기가 대류에 의해 증기 배출구(8)를 통해 외부로 배출되고 있고, 세척수가 분사될 때 발생되는 분사음이 증기 배출구(8)를 통해 외부로 배출되고 있다.In addition, even during washing, water vapor generated when the water is heated by the heater from the inside is discharged to the outside through the steam outlet 8 by convection, and the injection sound generated when the washing water is injected causes the steam outlet 8 to be discharged. Through the outside.

따라서, 내부의 고온다습한 공기 및 수증기가 직접 외부로 배출되어 비위생적이며 내부열이 직접 외부로 배출되어 열손실이 크고 세척소음이 외부로 배출된다는 문제점이 있었다.Therefore, the internal high temperature and high humidity air and water vapor are directly discharged to the outside, which is unsanitary and the internal heat is discharged directly to the outside, resulting in large heat loss and washing noise discharged to the outside.

한편, 이러한 문제점을 해결하기 위하여, 종래의 식기세척기의 증기배출구 개폐장치에서는, 도 3 및 도 4에 도시된 바와 같이, 증기배출구(8)의 중간에 마그네트(6)를 설치하고, 마그네트(6)의 단부에는 고무마개(7)를 부착하여 세척 및 헹굼시에는 고무마개(7)에 의해 증기배출구(8)를 막아주고 건조시에는 마그네트(6)가 동작하여 고무마개(7)가 하강하여 증기배출구(8)를 열어주는 구조를 갖는다. On the other hand, in order to solve this problem, in the conventional steam outlet opening and closing device of the dishwasher, as shown in Figure 3 and 4, the magnet 6 is installed in the middle of the steam outlet 8, the magnet 6 The rubber stopper 7 is attached to the end of the cuff to block the steam outlet 8 by the rubber stopper 7 when washing and rinsing, and the magnet 6 operates to dry the rubber stopper 7 when it is dried. It has a structure that opens the steam outlet (8).

그러나, 종래의 식기세척기의 증기배출구 개폐장치에서는, 건조시 증기배출구를 계속해서 열어주고 있어야 하는데, 이를 위해서 건조 시작 시점부터 건조 완료시까지 계속해서 마그네트에 전원을 인가하고 있어야한다. 따라서 전기소모가 많아지고, 마그네트의 계속 통전으로 인한 수명단축, 과열로 인한 발화등의 문제점이 있었다.However, in the conventional steam outlet opening and closing device of the dishwasher, the steam outlet must be continuously opened during drying. For this purpose, the magnet must be continuously supplied from the start of drying to the completion of drying. Therefore, the electricity consumption increases, there is a problem such as shortening the life due to the continuous energization of the magnet, ignition due to overheating.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 증기배출구를 볼에 의해 개폐하도록 하여 세척시 물분사 소음의 누설을 방지하여 소음을 저감할 수 있고, 또한 마그네트의 전기소모를 절감할 수 있는 식기세척기의 증기배출구 개폐장치의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, by opening and closing the steam outlet by the ball to prevent the leakage of water spray noise during washing to reduce the noise, and also to reduce the electrical consumption of the magnet An object of the present invention is to provide a steam outlet opening and closing device for a dishwasher.

상기 목적을 달성하기 위하여, 본 발명의 식기세척기의 증기배출구 개폐장치는, 세척조의 내부와 외부를 연통하는 증기배출구와, 상기 증기배출구의 내부에 이동가능하게 설치된 볼과, 상기 볼을 이동하기 위한 마그네트수단을 구비한 것을 특징으로 한다.In order to achieve the above object, the steam outlet opening and closing device of the dishwasher of the present invention, the steam outlet for communicating with the inside and outside of the washing tank, the ball movably installed inside the steam outlet, and for moving the ball It is characterized by having a magnet means.

이하, 첨부도면에 의거하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 식기세척기의 증기배출구 개폐장치는, 도 5 내지 도 7에 도시된 바와 같이, 도어(5)의 증기배출구(8)의 내부에 이동가능하게 설치된 볼(30)과, 상기 볼(30)을 동작시키기 위한 마그네트(20)를 구비하고 있다. 한편, 상기 증기배출구(8)에는 상기 볼(30)이 증기배출구(8)의 막음상태로 안착하기 위한 볼안착홈(21)이 설치되고, 상기 안착홈(21)에서 이탈되는 볼(30)이 쉽게 이동하여 증기배출구(8)을 열어 줄 수 있도록 안내판(22)이 설치되어 있다.The steam outlet opening and closing device of the dishwasher of the present invention, as shown in Figures 5 to 7, the ball 30 is installed to be movable inside the steam outlet 8 of the door 5, the ball 30 Is provided with a magnet 20 for operating. On the other hand, the steam outlet 8 is provided with a ball seating groove 21 for seating the ball 30 in the blocked state of the steam outlet 8, the ball 30 is separated from the seating groove 21 The guide plate 22 is installed so as to easily move and open the steam outlet 8.

식기세척기의 세척 및 헹굼단계에서는, 도 5에 도시된 바와 같이, 증기배출구(8)의 볼안착홈(21)에 볼(30)이 안착되어 증기배출구(8)를 막고 있고 마그네트(20)는 오프되어 동작하지 않고 있다. 이때 세척이나 헹굼시 발생하는 분사소음은 증기배출구(8)가 볼(30)에 의해 막혀 있으므로 외부로 누출되지 못하게 된다.In the washing and rinsing of the dishwasher, as shown in FIG. 5, the ball 30 is seated in the ball seating groove 21 of the steam outlet 8 to block the steam outlet 8, and the magnet 20 is Off and not working. At this time, the injection noise generated during washing or rinsing is prevented from leaking to the outside because the steam outlet 8 is blocked by the ball 30.

한편, 헹굼이 끝난 후 건조단계로 진입하기 직전에, 도 6에 도시된 바와 같이, 마그네트(20)가 동작하여 볼안착홈(21)에 안착되어 있던 볼(30)을 밀어내기 시작하여 증기배출구(8)를 열어주기 시작한다. 상기 마그네트(20)의 동작은 볼(30)을 안착홈(21)에서 밀어내어 주기만 하면 되므로 순간적인 통전으로도 볼(30)을 이동시킬 수 있다.On the other hand, immediately after the rinsing is finished, just before entering the drying step, as shown in Figure 6, the magnet 20 is operated to start pushing the ball 30 seated in the ball seating groove 21 to the steam outlet Start to open (8). The operation of the magnet 20 only needs to push the ball 30 out of the seating groove 21 so that the ball 30 can be moved even by momentary energization.

건조단계에서부터 운전이 완료될 때까지는, 도 7에 도시된 바와 같이, 마그네트(20)에 의해 안착홈(21)에서 밀려난 볼(30)이 증기배출구(8)의 안내판(22)을 타고 굴러 내려와서 증기배출구(8)를 완전히 열어준 상태가 되고, 볼(30)은 안내판(22)에 의해 이동이 방지된다.From the drying step until the operation is completed, as shown in FIG. 7, the ball 30 pushed out of the seating groove 21 by the magnet 20 rolls on the guide plate 22 of the steam outlet 8. When the steam outlet 8 is completely opened, the ball 30 is prevented from moving by the guide plate 22.

운전이 완료된 후 식기를 교체하기 위해 도어를 열면, 도 8과 같이 증기배출구(8)를 열어주고 있던 볼(30)이 안내판(22)를 타고 굴러 내려와 볼안착홈(21)에 안착되면서 증기배출구(8)를 막아주게 되고, 도어를 닫으면, 증기배출구(8)가 막힌 상태에서 운전을 시작하게 된다.When the door is opened to replace the tableware after the operation is completed, the ball 30 opening the steam outlet 8 rolls down the guide plate 22 as shown in FIG. 8 and is seated in the ball seating groove 21 as the steam outlet. Blocking (8) and closing the door starts operation with the steam outlet (8) blocked.

한편, 건조중에 도어를 열었다가 닫는 경우에는, 도어의 열림과 닫힘을 감지하여 도어의 닫힘과 동시에 다시 마그네트(20)가 동작하여 볼안착홈(21)에 안착되어 있던 볼(30)을 밀어내어 볼(30)은 안내판(22)을 타고 굴러 내려와서 증기배출구(8)를 열어주고 있게 된다.On the other hand, when the door is opened and closed during drying, the door 20 is closed and the magnet 20 is operated again to close the door and push the ball 30 seated in the ball seating groove 21. Ball 30 rolls down the guide plate 22 to open the steam outlet (8).

이상, 설명한 바와 같이, 본 발명에 따르면, 증기배출구내부에 설치된 볼에 의해 세척 및 헹굼시에는 증기배출구를 폐쇄하고 건조시에는 증기배출구를 개방함으로서, 세척시 물분사 소음및 수증기의 누출을 방지하여 소음을 저감할 수 있고, 마그네트의 전기소모를 절감할 수 있다.As described above, according to the present invention, by closing the steam outlet when washing and rinsing by the ball installed in the steam outlet and opening the steam outlet during drying, to prevent water spray noise and leakage of steam during washing Noise can be reduced and the electricity consumption of the magnet can be reduced.
